If you want to try some numbers out for yourself, here's a python script that calculates the blast radius: https://gist.github.com/colmmacc/4a39a6416d2a58b6c70bc73027bea4dc … . Try it for Route 53's numbers. There are 2048 Route 53 virtual name servers, and each hosted zone is assigned to 4. So n = 2048, and m = 4.

In that form it's pretty easy to see that the smaller S is relative to N, that Shuffle Sharding gets dramatically more and more effective! Convinced? I hope so!
